Semi-generic
Semi-generic is a legal term used in by the United States Alcohol and Tobacco Tax and Trade Bureau to refer to a specific type of wine designation. The majority of these were originally based on the names of well-known European wine-producing regions. Consumers didn't recognize grape varieties at that time and New World producers used the familiar names to suggest the style of wine they were offering for sale. U.S. regulations require that semi-generic names (for example, California champagne) may be used on a wine label only if there appears next to such name the appellation of "the actual place of origin" in order to prevent any possible consumer confusion.
Recent problems
Over the past thirty years, with the popularity of varietal labeling, semi-generic names have largely fallen out of use. They are typically only used on inexpensive wines sold in jugs or cartons and most of those now use the more popular varietal labeling.
The use of these names is a subject of some disagreement. Through trade agreements, the European Union has protected most of these names in its major export markets. In 1993, Australia agreed not to use European place names and France and Italy agreed to stop using the term Tokay, which is now reserved for Hungarian wines. The use of semi-generic names is beginning to become a problem for US domestic and foreign policy because as many American Viticultural Areas (AVAs) are becoming more popular around the world, they are seeking greater protection for their names inside and outside the U.S.
